EXCITED-STATE SUBSHELL POPULATION OF HYDROGEN-ATOMS AFTER TRANSMISSION OF RELATIVISTIC H- IONS THROUGH THIN FOILS

We present a theoretical study of the transmission of relativistic H- ions through thin carbon foils for a broad range of beam energies, Our study is based on a Monte Carlo solution of the Langevin equation des cribing electronic excitations of the atoms during the transport throu gh the foil. We present calculations for the subshell populations of o utgoing hydrogen atoms and we show that there exists a propensity for populating extreme Stark states. Our results are found to be in good a greement with recent experimental data. We analyze the effect of a lab oratory magnetic field on the population dynamics.
